I doubt there was porn at that time!

But could an elephant also have done it first?

I recently bought Dredge because I thought it was a cozy fishing game with some relaxed adventure bits. Oh was I silly.

Who (and when) was the first person in history to wank? And how did they find out?

Just to throw in some other options: you can easily convert basically anything to latex (and ultimately to Pdf) using pandoc. For instance, if you use Zettlr as your markdown editor, you can also use a citation software (eg., Zotero) and quickly invoke it using the @ character. Then, you can write your documents in Markdown and inline Latex and create Latex-powered Pdfs via pandoc. I use this approach to write scientific papers and it works pretty well.
